    Recently there have been a few optical communication articles in Practical Wireless. IIRC; the author ended up using FM.

    An IR laser will give you more range than IRLEDs but you'll probably need a visible laser to set up sighting.

    If you know of an end user disposals depot - IR lasers can be had from old laser printers, and visible lasers from supermarket checkout scanners.
